Good Morning,

I think I have the problem found and resolved.

Problem was located between the steering wheel and driver seat.

The noise would occur most every time my wife would leave for work in the morning. I would be out in front of car giving the ole wave good bye as she leaves first.

The noise has NEVER been heard when it restarts from an autostop sooooo I kinda figured it was how long the key was being held to start the car, be it from a cold over nite or whenever for that matter.

The fix has been to really be awake and hit the key FAST and let go even faster.

We too turn the car off in drive while it is in AS to prevent another wasted start of the engine.

See what happens if focusing on the key release, maybe your noise will stop too. Ours has not occurred since and it was a daily occurance.

Good luck

tony
